Watching the comings and goings of doctors, nurses and new patients was a mainstay of asylum routine; one can find it easy to imagine pale faces pressed against the block glass windows, staring out at the world moving past them.

When the factory’s production line was up for auction, many parts were removed, crated and labeled with big painted numbers to ease their removal by buyers. Not everything sold, however, so not one dark corner of the factory seems without a pile of dislocated industrial junk.

The top floor of the nitrating house was full of switches and breakers for the operation below, each bearing a label and number. Nowadays everything is printed, but when INAAP was built, all these signs were painted by hand.

Looking into the Argo Tunnel at its Idaho Springs portal. I was hoping to see tracks and a steel door, but found a busy crew of environmental workers installing a pipe between the bulkhead and new water plant.

Pillars painted red indicated firefighting supplies. Fire was a very common enemy of early rail facilities, and many roundhouses burned down because of a combination of dry wood, hot, fire-breathing machinery and countless oil-saturated surfaces.

Detail view of one of the fermenting tanks, still set-up for the distillery tours that no doubt took place when there last were such things. Nevertheless, the capacity of this tank multiplied across these all over the distillery floor really shows the power this company once had.

A reminder to the manlift riders to get off the belt before they hit their heads on the ceiling. This is the top level of the headhouse, where dust collectors would extract most of the grain bits from the air to reduce risk of explosion.

A primitive intercom system connected the various wards to their respective nurse’s stations. They looked hand-made and likely originated, in part, in the FFSH carpentry shop. They were often placed high, like this one, to be out of patient reach.

No wonder the factory shut down; everyone was scheduled to work 9 to 5 and the clock’s broken! (In all seriousness, this is/used to be a beautiful timepiece, especially for a utilitarian factory like this.

After crushing, these machines would float lighter material to the surface of the water, where it would be skimmed and discarded. Gold and silver laden stone would sink to the bottom, where it was collected for the next stage of processing. Leica/Summilux 35/Ektar 100

Thick glass windows allow workers to check the beet juice levels in this steel tank. You can tell by the reinforcement that it had a lot of liquid and had to hold against immense pressure. Kodak Tri-X 400/Leica M7.

Many of the higher floors were more or less demolished–usually more. These would have been condos had ‘The Arcade’ project come to fruition. Now there are simply wide open floors punctuated only by pillars and meaningless hallways.

These long curved corridors connected the wards. Locked doors on both of their ends were a security and comfort feature. Sounds and people would be sealed in their respective wards, as the hallways would act like beautiful airlocks; they were so long that it was unlikely that doors would be open on both sides at the same time. Portra 160.

In the ward for the criminally insane, this door was the most-worn. Nail scratches mark the area around the peep hole, the wood is gouged everywhere from thrown chairs and hard kicks, and a ominous blood-colored stain is visible where it dripped in the second inset from the bottom. Aside from the damage, the coloring in this section was very vibrant, though it was probably little reprieve for those who had to work here.

The individual ovens are skinny to allow even and fast heating of the whole interior. Numbers are cut into signs because no paint could withstand the heat or corrosive emissions from the coking process.

Before developers saw to cut and cut the flour mills inside Pillsbury, they stood at the ready beside various purposeful chutes the traversed the floors of between sorters. These machines were belt-driven by the power of Pillsbury’s Mississippi headraces and turbines, the force of which notoriously shook the building’s foundations themselves. The wheels would change the grade of the flour, or the size of the dust produced from crushing the kernels.
